Could you dare write that bracketing section in the page?
Worst scenario, it will be used in another place. Your credits, always.
You mean for the DOF stacking?
Sure.
So, am I right or maybe I should put these efforts on the already stablish wikia structure?
To change (a bit) or not to change, that's the question right now - I think.
Could somebody kindly answer it?
Well sure;
I've always thought the wiki pages were a bit over the top of my head when I first started messing around with CHDK. They're written by people well versed in CHDK as well as photography, and let's face it, most people with a P&S camera don't know the first thing about photography!
I believe that your efforts are just the type needed to make best use of the existing wiki as a foundation upon which to build to a much more user-friendly and inviting level.
At the same time, I warn you, that whichever you choose to do, be it to build upon the existing material or to start fresh in the creation of a preface "flowchart for dummies" (no disrespect to the "dummies"

, you will NOT STOP many of these people from asking repetitive questions. These are the very same people of the type that no matter how simplified that step-by-step poster is in the box with a new toaster, they still miss something and feverishly thumb through the "real" manual searching for a non-technical answer to their question.
...Then, alas, there is that technical support phone number on the last page. (People really do call that number!)
I guess my point is this:
While your efforts are sorely needed to update the wiki and make it more user/noob friendly, please don't expect the redundant questions to miraculously stop. You can lay out in perfect display all the information you could possibly share on this at their feet, free for the taking, but you can't force people to be smart enough or take the initiative to actually read and comprehend it.
Also, while you write the preface, perhaps you can keep in mind Graystar's CHDK manual.
